HAMBY, OF PAWHUSKA, OKLAHOMA, ASSIGHOR F ONE-THIRD T0 J. H- WARD, ONE-THIRD TO GEORGE IRWIN, AND ONE-THIRD TO CI-IARLEY HARRIS, .ALL OF PAWHUSKA, OKLAHOMA BATTERY TERMINAL CLAMP Application filed. February 10, 1931. Serial No. 514,863.

This invention relates to certain new and useful improvements in battery terminal clamps, and the primary object of this invention is to provide a clamp that may be readily and easily secured to the post of the battery, and as easily removed therefrom even after the clamp has been engaged with the post for a considerable period of time.

A still further object of the invention is to provide a battery terminal clamp, of such a construction that the same may so engage the battery post in such a manner as not to prevent the circulation of air about the post thus providing against corrosion, the accumulation of which renders so difiicult the job of removing the clamp from the battery post.

A still further object of the invention is to provide a clamp of the above mentioned character that includes a battery post engaging portion that fits over the post, and at its upper end projects beyond the corresponding end of the post when in final position on the post.

Other objects and advantages of the invention will become apparent from a study of the following description, taken in connection with the accompanying drawing wherein:

Figure 1 is a side elevational view of the clamp.

Figure 2 is a longitudinal vertical sectional view therethrough.

Figure 3 is a bottom plan view thereof.

Figure 4 is a fragmentary end elevational view thereof.

With reference more in detail to the drawing, it will be seen that my improved clamp comprises a pair of complemental members 1 and 2 respectively.

The member 1 adjacent its upper end has integral therewith a longitudinally split lateral socket or sleeve 3 for accommodating one end of the conductor wire 4.

The upper portion 4 of each member 1 and 2 is preferably solid, while the lower portion 5 of each member is substantially semi-cylindrical in cross section and is provided on its inner concaved face with screw threads 6.

The members 1 and 2 are connected by a pair of oppositely disposed combined conector and spacer plates 7, and the plates 7 are connected by pivot bolts 8 extending through the members 1 and 2.

The member 2 has provided in its upper solid portion 4 a threaded aperture in axial alinement with the bore of the sleeve 3., An adjusting screw 9 is threaded through the bore and the free end of the screw is adapted to abut the solid portion 1 of the member 1 for urging the members 1 and 2 relative to one another about the pivot bolt 8 whereby the threaded portions 5 of the members are forced into clamping engagement with the post of a battery (not shown). A lock nut 10 is threadedly engaged with the shank of bolt 9 for securing the bolt 9 in its fixed position to insure tight contact of the members 1 and 2 with the battery post.

It will be apparent, that when the clamp is in use, the same is passed downwardly over the top of the battery post, the post being received between the semi-cylindrical portions 5 of the members 1 and 2. Screw 9 is then rotated for engagement with the memher 1 whereby the members 1 and 2 are rotated relative to one another for moving the portions 5 of the member inwardly toward one another and into engagement with the battery post. Threads 6 provide teeth for engagement with the battery post. When the clamp is thus applied to the battery post it will be seen that the confronting portions of the members 1 and 2 will be retained in slightly spaced relation thus insuring a circulation of air about the post and clamp. Such freedom of air circulation is conducive to preventing corrosion.

Even though I have herein shown and described the preferred embodiment of the in vention, it is to be understood that the same is susceptible to changes modifications and improvements coming within the scope of the appended claims.

Having thus described my invention, what I claim as new is:

1. A battery terminal clamp comprising in combination a pair of complement-a1 members having corresponding portions semicylindrical in cross section for accommodating therebetween the battery post, connecting bars pivoted at their ends to said members, and a bolt threaded through one of said members and engageable with the other of said members for urging the cylindrical parts of said members into engagement with the battery post.

2. A battery terminal clamp comprising in combination a pair of complemental mem- L0 hers. respectively comprising a relatively solid lportion, and a substantially semi-cylindrica portion, a pivot bolt extending through each of said members intermediate the ends of said members, connecting plates engaged at their ends with said pivot bolts, the semi-cylindrical portions of said members adapted to accommodate therebetween a battery post, and means for urging said cylindrical portion into engagement with the battery post.

3. A battery clamp comprising a pair of complemental members respectively provided with a semi-cylindrical portion, said semic ,lindrical portions constituting jaws for c amping therebetween a battery post, a pair of oppositely disposed parallel bars pivoted at corresponding ends to said members for retaining said members in relatively fixed relation when the members are disposed par- $1101 to one another, one of said members having a conductor cord accommodating sleeve integral therewith, and the other of said members having a screw threadedly engage/d therewith and adapted to engage the as rst mentioned member for urging said members about their pivots.

In testimony whereof I afiix my signature.

JOSEPH E. HAMBY.
